Abstract

The invention belongs to the technical field of composite materials, and relates to a thermoplastic composite material floor and a preparation method and a preparation apparatus thereof. The thermoplastic composite material floor consists of thermoplastic resin and continuous filaments which are dispersed in the thermoplastic resin in parallel along the horizontal direction of the floor in a lamelleted shape. Compared with the prior art, the preparation method has the advantages that the technology is simple, the operation is easy, the floor can be directly formed, the forming is easy, and the forming period is short; compared with the defects of mutability, easiness in wear and the like of the traditional solid wood floor and wood plastic composite floor, the floor obtained by the preparation method has the advantages that the deformation resistance is more excellent, the permanent deformation does not occur, the durability is better, and the weather ability and the corrosion resistant capacity are better.

Description

technical field [0001] The invention belongs to the technical field of composite materials, and relates to a thermoplastic composite floor and a preparation method and equipment thereof. Background technique [0002] At present, the floors sold on the market are mainly various wooden floors, such as solid wood floors, laminate floors, wood-plastic composite floors and the like. They need to use a lot of wood, wood is a scarce resource, its price is rising year by year, and the cost of raw materials for wood flooring is getting higher and higher. At the same time, extensive use of timber is not conducive to the protection of limited forest resources. In addition, there are many performance defects in wooden flooring. For example, it is easy to shrink and swell when wet, resulting in warping and deformation. Easily corroded, prone to insects and moths. Laminate flooring and wood-plastic composite flooring produce a large amount of toxic gases such as formaldehyde during th...
